Scientists with the National Institutes of Health are looking for up to 100 volunteers to have the virus sprayed into the noses, according to The Associated Press. Those willing to take the risk will be compensated up to $3,000.

Restaurant worker Daniel Bennett, 26, volunteered for the study.

"I received a very scolding email from my mother," Bennett told The AP.

A few days after being exposed to the virus, Bennett had the runny nose and achiness of mild flu.

Researchers said they hope to determine how younger adults fight off the flu. They noted that some people in the study didn't get sick, despite low antibodies against the virus, so something else may be protecting them.

This sort of flu study hasn't been undertaken in the United States for more than a decade, before scientists had such sophisticated tools to measure how the body reacts.

Bennett said he had mild symptoms for a few days, and he spent the time studying, watching TV and playing games with the four other study participants he was with.
